APPARATUS FOR TREATING GASES WITH LIQUIDS AND LIQUIDS WITH GASES.

Specification of Letters Patent.

Patented Oct. 1, 1907.

Asplicatiou filed June 5,1905. Serial No, 263,818.

My invention has directly for object an apparatus wherein waterm y be subjected to the piirifying action of ozone or ozonized air and 1 shall herein desgibe the apparatus with special refers co to that use. But it will be obviou's that the apparatus is oi much wider applicability, as, to other liquids and gases,and that its function, in some applications, may be the treatment of a gas by subjecting it to intimate contactwith a liquid, instead of the contrary function herein pegticularly described.

In subjecting water to the action of ozonized air, it is important that the distribution of the aircthroughout the water be thorough-so that no impurity in the water will escape the oxidizing contact of the ozone; that the operation be continuous and, if need be, rapid; that the air, rendered impure by its action upon the water impurities, be separated out from the wat iland that the action of the apparatus shall, by automatically operating means, he maintained at all times constant. To

attain these desirable objects I have devised a form of ozonizing tower which I will first fully describe with reference to the accompanying drawings before proce'eding to point out in the claims the novel elements and combinations.

In said drawings: Figure 1 is a sectional elevation of a water ozonizing tower embodying 'rny improvements.

by the line 2-2 Fig. 1.

with the main or source of water supply.

Fig. 2 is a transverse sectional view on 'a plane indicated The tower comprises the casing or pipe 1 into which water to be purified is introduced at the top or upper part of the casing, as by a pipe 2 suitably connected The height of the tower and bf the water column therein, as well as the pressure employed in the system, will.vary with conditions of ozone generating apparatus and quantity rand purity of the water supply, and the proportions the Water is introduced under pressure at the lower part of thetower through the pipe 3which has within the tower an upturned end or nozzle-4, preferably located in the exact center of the tower anddischarging the ozonized air, therefore, in a stream equidistant from the walls of the tower, Arranged transversely in the tower at a suitablepoiut below its upper end, 'to insure that the water shall have sufiicient treatment with the ozone 7 and the circular horizontal portion 8. The annular portion 6 has perforations 9 to permit the ozonized water to flow through the diaphragm, while the portion 8 is a screen having very minute apertures or perforations to permit theozonized airto pass through it into the water in the upper part of the tower. .The neck 7 is made of such height as to allow such difference be tween the head of water on the screen-8 and on the annular part 6 of the diaphragm as to insure the flow of the water through aperturesQ in the annular part 6 instead the body of water, will prevent the-passage of the water. The oz 'onized air passing up in ,the'watertower 1 will subject .to its oxidizing action all of the impurities therein and then escapes or is led off through the pipe or outlet 10 at'top of the tower.

After passing through the annular part 6 of the diaphragm the water flowsout at the bottom of the tower through the delivery pipe 11 which is, preferably, as shown, ledup to a point sufiicientl'y above the bottom of the tower to water-seal the outlet .and prevent the escape of th e ozonized air. There is also thus afforded between the surface of the/ water in the lower part of thetower and the diaphragm 5 a chamber 12 in which the water will setfree any air which has been carried down with it. The air in the chamber 12 being at the same pressure as that issuing from the in1et4 will be again carried with the latter up through the screen 8 and so again be brought in contact with the descending water in the tower above the diaphragm,

To maintain the constancy of the depth of water in the chamber. 12 I place in the outlet 11 a valve 13 controlled by the float 14 resting on the water in said chamber, so that when the depth of said water increases the valve will open the outlet allowing the water to be more quickly discharged, and on decrease of depth of the water, a contrary movement of the valve takes place, partly or entirely closing the outlet.

It is desirable that the depth of water'over the diaresistance o the passage of the water through the diaphragm. 'To automatically adjust this'ring in harmony with the speed of the water supply'l may as range at the side of the tov' er a standpipe 17 having the cylindrical horizontal pertidnlB connected with the tower immediately above the part the diaphragm.

phragm 5 be maintained constant, to secure completein. the said horizontal portion is arranged a piston 19 connected by the rod 20 with the ring 15. Sufiicient water is placed in thestandpipe 15 to force the piston inwardagainst the resistance of the columnof water in 5 the tower 'above the diaphragm if the said column should fall below the proper normal height and thereby close toa greater or less extent the apertures in the part 6 of the diaphragm should the head of water in the tower above the diaphragm 'diminishowing to the falling off of the supply. t

, It is obvious that many modifications may be made inmy invention'without departing from its essential elements hereinafter claimed, and I therefore, do not wish to be considered as limiting myself to the exact details of construction or exact application of the invention herein shown and described.

Having thus described the invention what I claim as new and desire to secure by Letters Patent is:

1. In apparatus of the character described, the combination with a chamber adapted to contain a liquid, and a chamber adapted to contain a gas: of a gas communication from the gas chamber to he liquid chamber, a liquid communication from \ie liquid chamber to the gas chamur, and means for maini'ainim, the liquid pressure on'the liquid communication above the gas pressure and on the zas communication below the gas pressure.

2. In apparatus of the character. described. the combination with a tower adapted to contain a body of liquid above and gas under pressure below, and an intermediate transverse partition having two perforated portions at dilfercnt depths in'said body of. liquid, and means for maintaining the liquid-pressure on the lower perforated portion of said partition ab ve the pressure oi said. gas, and on the upper perforated portion thereof below the pressure of said gas.

In Liparatds oi the character described, thecombination of a tower portion, an inlet" for gas at itslower portion, :1 dinp'hragm having'a-n apertured portion for the passage of gas, and means for regulating the passage of liquid hination with a vessel adapted to contain a body of liquid above and gas under pressure below, and an intermediatetransverse partition adapted to support saidbody o1! C the liquid, above said;

tion 'of lesser depth below that of'the gas and a pressure on the communication of greater the gas.

4. In apparatus of the character described, the com binatlon with a vesselprovided with achamber adapted to contain a body of liquid and a chamber adapted to con-- tain a gas under pressure; of means of communication from the gas chamber into said body of liquid at a lesser depth in said body of liquid,-means of communication from said'hody of liquid into said gas ehamberat', a, greater depth in said body oi liquid, and means controiled by the depth of liquid for maintaining the pressure on the communication of lesser depth lower than the gas pressure and on the communication of greater depth higher than the gas pressure. i

5. 1n apparatus of the character described, .the comhuving an inlet for liquid at its upper depth above that of through said diaphragm controlled by the height of liquid above the diaphragm.

' 6. In apparatus oi the character bination of a tower having a perforated dlaphragnfi 'means for supplying liquid abav'e said diaphragm and 'gas below it, and means for contrdlling the passage of liquid through said diaphragm controlled by the liquid above the diaphragm.
